SNAP-FASTENEB.

Application filed November 20, 1916.

To all whom it may concern Be itknown that I, KARL G. DIETERICH, a subject of the German Emperor, and a resident of the city of N w York, in the county of Kings and State of New York, have invented certain new and useful linprovements'in Snap-Fasteners, of which the following is a specification.

The'present invention relates to separable fasteners of the head-and-socket type, commonly known as snap-fasteners. It pertains'more'particularly to a fastener wherein a rigid head engages with a resilient socket.

The main object of the present invention,

is to produce a fastener of the type mentioned, which is simple in construction, efficient in operation, and which can be manufactured on a commercial scale, or in other words one which is not so diiiicult to make as to be beyond the reasonable cost of such an article.

Another object of the invention is to so construct the fastener that its elements can be produced by stamping operations, and with the least possible waste of material.

A further object of the invention is to provide a fastener that can be produced by the aid of very simple dies and machinery, thereby greatly reducing the initial cost of the manufacturing plant.

'With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement, and construction of parts hereinafter described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure l is a top plan view of the female section of the fastener; Fig. 2 is a section taken on line 2-2 of Fig. 1; Fig. 3 is asection taken on line 33 of Fig. 1; Fig. 4 is a side elevation of the male section of the fastener; Fig. 5 is a bottom plan view thereof; F ig. 6 is a plan view of two sections of a garment secured together by the Specification of Letters Patent.

fastener, forming the subject matter of the present application for Letters Patent; 7 is a section taken on line 77 of Fig. 6, on a larger scale; and a section taken on line 8-S of Fig. 6.

In the drawings the numeral 10 indicates theniale member of the fastener, and the numeral 11 the socket or female member thereof. The'male member comprises a disk 12, upon which is centrally formeda stud 13, having atits free end a head l t. The diameter of the head is somewhat larger than that of the stud, for the well-known purpose. In the disk are formed openings 15, to permit the male member to be sewn to a garment 16.

The female member 17 consists of a single element. This element is made, preferably, in the form of an elliptical plate, or, in other Words, an oblong plate member having rounded ends. The plate is provided with a downwardly extending flange 18, all around. The height of this flange is such as to accommodate the head 1% upon the stud of the male member. The plate is dished or concave in the direction in which the flange thereof extends. In the plate is provided a substantially elliptical opening 19. The major and minor axes of this opening coincide with the major and minor axes of the oblong plate. In the major axis of the oblong plate member there are provided slits 20, which merge into the elliptical opening 19 therein. The length of the minor axis of the elliptical opening is slightly less than that of the diameter of the head 14: of the male member, while the major axis of said opening is considerably larger than the diameter of said head. In the plate member are formed apertures 21., through which is drawn the thread by which the female member is secured to the portion 22 of the garment. The female member is formed by stamping operation, and is made of a thin sheet material, such as metal. By forming the slits 20 in the plate member, the edges of the elliptical opening therein are made yielding or resilient.

The operation of this device is as follows: As the head 14 of the male member is inserted into the opening 19 in the female element, it engages the edges of the said opening, which yield to allow of a passage of the head, and immediately spring back into their normal positions into engagement with the stud 13, forming thus a rigid hold which will prevent accidental separation of the fastening. The same may be disengaged by a sudden pull upon either part away from the other. 1

Attention is called to the fact that, if either one of the two elements of the fastener is shifted relative to the other laterally in the direction of the major axis of the opening 19, the head lat of the male member will be wedged in said opening, thereby effectively preventing a disengagement of the male member from the female member of the fastener.

From the foregoing it appears that the construction is very simple, cheap to manufacture, and that the female member comprises a single element, so that no assembling of parts is necessary as in devices heretofore in use.

In attaching the female member to the garment it can be picked up indiscriminately and secured to the garment without paying any attention to which end thereof will be adjacent to the edge of the garment. It is to be observed that, inasmuch as the female member of the fastener is dished or 'concaved, as above described, the male member will easily find its way into the opening thereof.

What I claim is: V

In a snap fastener, a female member comprising a plate having an oblong opening, said plate being provided all around with a flange extending at an angle to the body portion thereof, said plate having slits in thema-jor axis of said opening, said slits merging into said opening, and said flange having apertures.

Signed at New York, in the county of New York, and State of New York, this 15th day of November, A. D. 1916.
